The film, based on the actual events recorded in history as the Night of the Pencils (La noche de los lápices), tells the story of seven students who, after protesting for lower bus fares for students in the city of La Plata, were abducted in September 1976, during Argentina's last dictatorship (1976 - 1983), and subsequently disappeared.

The civic-military dictatorship of Argentina called this period of state terrorism in the country the Dirty War, as a part of Operation Condor.

The motion picture was based on the non-fiction book, La noche de los lápices, written by María Seoane and Héctor Ruiz Núñez.

The book profiles seven high school student activists from La Plata, including lone survivor Pablo Díaz, who gives the authors his testimony.

In daylight, the once-beautiful, now crumbling buildings, including the high school itself, become emblems of a country falling apart, not knowing what to preserve from its past.
